STUD .AND PARTITON CONSTRUCTION FOR BUILDINGS Application led September 21, 1929. Serial No. 394,214.

My present invention refers to stud and partition construction for buildings of various kinds, more especially oiice buildings, hotels, and other large structures in cities.

Among many advantages and objects that might be enumerated, 1 mention sound-deadening; ease, facility and speed in erection; cheapness of material and arrangement of details strength and rigidity; and more especially the sound-proof, simple and efficient character of the partition construction, including a novel and rigid stud, together with novel air-spatial plans; all combined to promote economy without the sacrifice of architectural advantages.

With these leading objects in view, and others that will appear as I proceed to discuss the details and their relation and use, it may be said in general that the invention consists in the construction, combination, and

arrangement of parts, and numerous peculiarities thereof, substantially as will be hereinafter described and claimed.

1n the accompanying drawings illustra-ting my invention:

Figure 1 is a horizontal section of a selected portion of my improved building construction, showing the relation that the various parts sustain to each other in a` partition wall.

Figure 2 is a vertical section of the complete partition on the line 2, 2, of Figure 1.

Figure 3 is a perspective view of one of the studs. f

Figure 4 is a horizontal sectional plan of the stud on the line 41 4, of Figure 2.

Figure 5 is a segment of the partition wall, indicating more or less in conventional outline the main features of such wall.

Similar characters of reference denote like parts throughout all the different figures of the drawings. Y A

A leading feature is the stud or upright post A, which is formed of steel or other metal in a right-angled channel or similar angular form like a. horizontal U or l.. Stud A has therefore the three sides 1, 2, and 3, which may be about the same in width. Qne of these sides or webs, as l, is rebent on itself as 4, and 5@ extended beyond the intermediate side 2 to secured together.

provide a projecting member 6; the members 6 and 4 lying in the same plane and constituting an integral member double the width of either of the single parts 1, 2, or 3, so that these two parts 3 and 4, 6, are parallel to each other, and part 4, G, is twice as wide as the other part 3, so that on one side the stud presents a face much wider than it does on the other side. This helps in holding the wall board against the opposite side of the stud. The side 6 at intervals has integral lugs 5 cut out of the same and turned at a right angle to the face of side 4. See Figure 2. rlChese lugs 5 have each a pair of perforations a and for a purpose that will appear. Lugs 5 lie in the same plane as intermediate side 2, because they are turned out at a right angle at the point where the rebent side 4 merges into the projecting side 6, the sides 4 and 6 being integral with each other as stated.

Although I describe the entire channeled stud as made in a single piece, yet it is quite obvious that it may be made in several parts Thus the U-shaped part might be one piece, and the combined side 4 and G might be another plate secured to a side of the U-shaped member, but providing the perforated lugs as before.

rTaking this unique and novel stud feature as the main factor in the partition construction, I proceed to describe how it is utilized in building up a sound-proof wall, as shown in detail in Figures 1 and 2. There is a plurality of these studs erected between sections of wall board, the outer sides of which are overlaid with plaster and metal lath, while between these sections are one Ior more dead air spaces 21 and 22, as narrow or as wide as experiment may suggest to be useful and 1 adequate.

In the main frame of a building the ceiling of one storj7 will have angle beams C or some equivalent members with which the upper end of each stud may be connected, said beam C having a horizontal leg or web c1 and a vertical leg C, both of which may have the usual bolt or rivet holes. Also the tiooring will have similar L beams D or equivalent pieces to which the lower ends of the studs .may be secured, these L beanie having hert zontal legs or Webs Z and vertical legs d1 provided With the usual bolt or rivet holes. The studs When placed vertically Will reach from floor to ceiling, but as ceiling heights vary in different structures it is necessary to have an extension member oil oneend of each stud which can be adjusted more or less to make the stud longer or shorter. This adjustable part Iusually place at the top, and it consists of a channel iron B having three sides like the three sides of the stud member A, said channel member B beingslightlyvsmaller thanA so that it will lit inside of A. See Figures 2 and 4.

The extension member B is secured Within stud portion Alby a bolt or other device 20 which passes through a slot 19v in the intermediate part of channel piece B and a coinciding slot in stud A, the slots being long enough to permit of considerable adjustment so that the entire stud may be caused to have just the right length to reach from the licor to the ceiling, andwhen so placed the nut on bolt 20 can be tightened and the parts held togetl'ier. rIl`he upper end of top member B hasa perforated lug 23 similar to and aligned Vwith lugs 5 all serving the same purpose ;y and top is placed rsnugly Within the angle of beam C and securely bolted or fastened. Likewise the lovver end or the stud is bolted or fastened to the L beam D, Whose sides d 'and-dl have as many bolt holes as may be needed to bolt it in pla'ce. In` assembling the partition details thereforel first erect a suitable number of studs s'ay one series, and after they are secure place against and with them the Wall boards.

S0 far as the board featuresvare concerned, I reserve the right to use boards of any desired material, natural or artificial; either Wood, or metal, or a i'ibrous substance,jor a combination of them, or a manufactured or natural composite substance; usually rather thin 'and light, and in prepared sheets or sections/suitable for the purpose.

l/Vhen a feiv studs are erected at suitable intervals apart, as showvn in the top rovv of stu'ds in Figure 1, with the lugs 5 projecting in the saine direction outvardly, `the outer wall boards 13 and i4 will be placed in a line `with their vertical edges in contact with the lugs 5. The 'Contact may be tight, or loose and easy as preferred; The board 1 3 rests against one side lof the lugs 5 and also against the adjacent face of the studiwhile Lon the opposite side of the lugs 5 the edges of other boards le are placed, ivho'se' sides are also Aagainst the adjacent faces or theA sfu-d5.

rvEhen throughthe perforations et vthe lugs 5 are driven the Wedges 7 the outer side of the boards 13 )and V14, so that the bbards are closely fastened to the studs and inline with eachother. After these parts are thus placedthe plaster coat 9 is applied to boards 13 and 1e in connection With the metal lathing 10 Which supports the plaster.

The lathing 1() is fastened across and to the lugs 5 by pieces of Wire 8 Wound through the meshes of the lath and the perforations Z) of the lugs 5 and the end of the Wire tightly twistedv together.' 1 ,f l z j On the lside of the boards 13 and 14 opposite to the plastered coat 9 is an air space 21 equal in size toI the Width of the channel beams A that form part of the studs. Next I support board 15 on the other side of these studs against the legs. or Webs 3 of the channel pieces A, and against :board 15. I also employ a "series of flat boards 16 so that two thicknessesfof boards are used here, their ends overlapping, but preferably theL tWo thicknesses are no t continuously so, but their ends overlap toA alloyv at least a As ing'le unbroken thickness the Whole length of `the partition, and the Overlapping 1s opposite to vthe studs. Boards 1 5 and 16 form the other side of an air space Ql.

The construction I havev just described for one roiv of studs isduplicated with ,another vroW of studs toinake the full thickness of the partition With another air space at @Zon the side of theiniddle line of boards 15 and 16 opposite t0 ,the airspace 21. This is shown fully in Figure 1. j 011 .this Side in the alfngemlflt 0f th. S is that the studs arereversely placed, that the channels A therein openin a direction 'opposite to Vthe direction of thelopeningin he exception the channels in the first row, and the lugs 5 llOieLClt thi@ ether Wayo i,

This arrangement hoyvever is merely a preferred detail of location for the studs and in order to produce a more balanced assembly, and I am thereto but I nay vary as much as I please. rI'he boards 16 are closely against the second roivofstuds. Qnthe other sidebf the studs are the boards 17 and 18 arranged in amanner silnilar t0 the boards 13 and 1 4 locked by ,Wedges 7 to the studs. The outside surface vof boardsl? `and 18 is covered With aplaster coat with 'metal lath 12.-, the latter held by the Wires 8 in the perforated lugs 5. .j i,

While n y impryed partition @instruction is inreeffectually soundiproofed by a complete construction as I have just described Where ifleuble. easement@ employed, yet an efficient result isattaineduby ythe use of one air space and iny invention is broad enough to cover a single air chamber and a ivall Withhalf the features .that

are duplicated in the foregoing recital. Furin meer t5 suit the invention for use wlerby no in eans conlined.

ever it is adapted to be specialized for the needs of individual cases.

What I claim is:

1. In building construction, a stud having a right-angled channel formed by two parallel webs and an integral intermediate member, another member alongside one of said webs and widened to form a surface substantially larger than said web, the outer edge thereof being incut at intervals and the sections between the cuts being bent at an angle to form lugs in the same plane with the intermediate member of the channel, said lugs being perforated, and fastening means for wall boards being passed through one perforation, and fastening means for lathing being passed through another perforation, so that the lugs and fastening may hold the constituents of the wall close against the studs.

2. In building construction, a stud having a channel formed by two parallel webs and an integral slotted intermediate member, one of said webs being rebent on itself and widened to form asubstantial wide surface, the material of the outer edges being cut at intervals and the sections between the cuts turned at an angle to form lugs that are provided with means for securing wall boards to the studs, said lugs being in the same plane with the intermediate member of the channel, in combination with a channeled and slotted extension member of smaller cross section than the stud that slides in the channel of the stud so as to adjust and regulate the length of the latter to the required distance between floors, said extension having a lug in the same plane as and cooperating with the other lugs, and bolting means passing through the coinciding slots to secure the extension piece to the main stud at the proper point.

In testimony whereof I hereunto afX my signature.

FRED J. SERSEN.
